Le Nez in this context means the aromatic palette, through a metonymy. Not sure it translates well to English, since this stylistic device may be very French in its usage (another example would be Musée Rodin's exhibition Rodin, la main révèle l'homme)

It translates exactly. In oenology, it is indeed referred to as the 'nose' of the wine in English. I've also heard it used for whiskey.

Well then, the translation is not an issue
